Intermittent dropped internet connection on Fibe network Gigahub

[Zeronadanil]

I switched from DSL to Fibe and my DSL service has been very stable. Since switching to Fibe I have these issues:

* my VPN is disconnected frequently

* real-time gaming connection is interrupted and after a few seconds is restored (no VPN)

* the TV service has glitched out on occasion

Since this issue did not exist on DSL it is likely something on the Fibe network. I did reboot my Gigahub, called customer tech support and they were not able to identify the issue. Everything else is working great just the network connectivity is the issue. I have done a traceroute to various IP's and noticed that the on the 142.124.127. network various IP's have >60% packet-loss. One problematic IP a lot of my traffic is routed to is 142.124.127.165 (67% packet loss).

I am a Network Admin working from home and having these types of issues disrupts my work.

The GigaHub has a connection test. That's a good one to run to see if there is an issue from your Gigahub to the internet. My issue was really annoying because the internet kept disconnecting from my Gigahub to my PC using ethernet even after I replaced the ethernet cable and network card and upgraded firmware and drivers on my motherboard. The issue ended up being is that I used a flat CAT6 cable for some reason my GigaHub didn't like that cable, I tried a couple. What fixed the issue was when I bought a CAT8 cable. Now I don't have this disconnecting issue anymore.

I use my own ethernet switch and I use my own mesh wireless which is better than what the GigaHub provides. TheGigaHub has a built in connection test - that's good to run. Also has a log, it showed me which ports were disconnecting and it was always my CAT6 cable port.

If you use the 10 Gbps port on the gigahub and connect using a 10 Gbps ethernet card, you could indeed have an issue using a CAT6 cable. It depends a bit on the length and the "source" of the cable.

I would recommend a cable from a reputable company.

Here's a list of CAT cables and their rated speeds, and limitations.

I had a similar issue on my Bell Home Hub 4000.  If you have any, try removing any USB devices you have plugged into the Home Hub...then reboot.  Bell pushed a firmware update late in August 2025, that caused the issue for me.

Hey Anonymous,

I have been going on with the same issue since march of this year and i have gotten 8 new modems and 2 techs and one of the 2 didn't even register the notes for what he did which was nothing but replace the modem and tell me its my enviroement that is causing the issue. So lets back track to March /2025 all is working well and one day im working from home and i get disconnected 4 times in like 3 hours and i didnt think of an issue was happening as the modem was back online and all was ok. Next day disconnected 15 times in a span of 4.5 hours and thus i called bell they said all was ok and that they have rebooted the modem and also did an update on the modem.well this has been the same answer and i mean tech and case managers. They have replaced my modem 8 times including now sending me the new Giga Hub 2.0 as they said it will fix all my issues. Well has it no, my security system goes off line at all hours of the day after the network goes offline and rings back online. The Case manager said they have no abiliy of fixing anything and no other team that they can escalate the issue to but an onsite tech which is so disturbing as they keep this up and i will have totalled the largegest number of calls to the Bell Support line. My issue is both Wi-Fi and ethernet connection and no its not the modem as this is what was advised by the last tech that was at my house a week ago and stated this is a network config issue with the device / account. The case manager didnt know anything about that but hey i gave him the tech's cell number and tild him to call him and get him to explain the finding as im not doing the work anymore. I have been dealing with this for 9months and after reading your post im going to reach out to CCTS (Commission for Complaints for Telecom-television Services) as it seems to be that beel doesnt care abotuits clients issues once they have the account on the books and they will find any way to just advise clients if you have a network issue reboot the modem. I will say thats not a fix for all and this case its not and this issue like your seem to be a bigger problem and by the sounds its someone not doing the right job higher up on the tech support / infrastructure later. 

Extra info:

- No Bell Pods

- Issue on both wifi and ethernet connection

- no error codes on the modem screen and for the log ont he modem its pathetic when comes to providing details. I have seen other modems including Bells first Home Hub modem use to provide better info for troubleshooting

- SSID is unique 

- All devices connected are getting disconnected and no chnage to the list of devices i have had. The number and type of device are the same since the day i got Bell Fibe at the resident and the same since March when the issue started

Well Im going to be contacting CCTS as this issue is getting out of hand and no one at Bell is taking this serious and after almost 9 months im starting to loose my mind with this garbage.

@MRJ  I hate to tell you, but if you file a CCTS complaint (which I did), they’ll just offer you some credits and won’t actually troubleshoot the issue. The Bell techs basically told me they don’t support third-party hardware (fair), and that if the Giga Hub 2.0 didn’t solve my problem, I should consider cancelling. Unfortunately, I need to use my own hardware — I have over a dozen wired connections in the house and the Giga Hub only offers a few usable ports.

After months of troubleshooting, I noticed the system logs on the Giga Hub were full of continuous IGMP join and leave messages, pointing to problems with how the hub handles multicast and IGMP snooping. Devices like my DVR, SkyBell, MyQ, and other smart home tech were dropping offline randomly or failing to reconnect after a few hours — especially those relying on 2.4GHz Wi-Fi and multicast traffic.

Here's how I finally got things working:

• Disabled DHCP on the Bell Giga Hub

• Enabled DMZ, pointed to a static IP assigned to my Omada router (192.168.1.10)

• Let the Omada router handle all DHCP, NAT, and IGMP snooping

• Created a dedicated 2.4GHz-only Wi-Fi network for IoT devices, separate from

Hey @Daveyboy,

So what your saying this is Bell device issue ? The device that they have cant multicast and IGMP snooping correclty? 

[Vanadiel]

No, what he said was that the Giga Hub log was full of continuous IGMP join and leave messages.

This might be of help to you.

To be more specific:

What types of IGMP messages are there?

The IGMP protocol allows for several kinds of IGMP messages:

• Membership reports: Devices send these to a multicast router in order to become a member of a multicast group.
• "Leave group" messages: These messages go from a device to a router and allow devices to leave a multicast group.
• General membership queries: A multicast-capable router sends out these messages to the entire connected network of devices to update multicast group membership for all groups on the network.
• Group-specific membership queries: Routers send these messages to a specific multicast group, instead of the entire network.

In other words, join and leave messages are based on devices that want to join/leave, not on what the router does.

Thanks for your comments. If you need to use many wired connections, an unmanaged 10 Gb switch with sufficient ports my be useful to you. Connect to the 10 GB port or any other port.

For the last month, my internet drops out for minutes at a time, several times per day. When I log into the modem, there are no errors, the internet appears "UP" but the ping test shows: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss)

Anyone at Bell know what's going on here? I'm on my third modem (two replacements did not resolve the issue).

[dks]

Thank you for your question. Is this a wired or wireless connection to your Giga Hub? If your modem is fine, I would look for issues with your network cable (replace with a Cat 6 cable) or your wireless device. 

[User819]

Does everyone with Bell internet have CONSTANT drops of internet service. Tech calls, new modem still CONSTANT internet resets. And they raise the rates twice a year, a joke, thank god I have cellular with another company otherwise I would have no internet.

[dks]

Thanks for your concern. There are many reasons for a constant drop of internet service. It would help us to assist you if we had more information.

• What speed tier or package do you have?
• What hub do you have?
• Are there any error messages displayed on the hub screen? 
• Are you seeing drops on a wired or wireless connection or both? 
• Can you run a speed test from the hub interface using these instructions and report the result? 

Looking forward to hearing back from you. 

[User819]

It’s hopeless and worthless. I’ve reset the modem 1000 times. It works for an hour, 10 minutes or 10 days, no pattern. Tech checked last year, fiber splice, new modem same result. Your internet is THE WORST.
